5 numbered steps. Works for any shape you can cut into standard pieces. Split into standard shapes — Rectangles, triangles, circles.

The centroid is geometry only. It coincides with the centre of mass just when the density is uniform.

Who is the Finding a Centroid poster for?

Finding a Centroid belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning statics & dynamics can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Finding a Centroid poster?

Before any bending calculation, because the neutral axis sits on the centroid. A wall chart earns its place by being glanceable from where the work is happening, so Finding a Centroid belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Finding a Centroid?

Dry Friction, Energy or Momentum? and Static Equilibrium sit alongside Finding a Centroid in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.

Is the Finding a Centroid poster free to download and print?

Yes. Finding a Centroid downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.

What size does the Finding a Centroid poster print at?

Finding a Centroid is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Finding a Centroid loses nothing.

Finding a Centroid, step by step

Works for any shape you can cut into standard pieces.

Split into standard shapesRectangles, triangles, circles. A hole counts as negative area.
Set one axis systemOne origin for the whole figure, usually a flat outer edge.
Tabulate area and positionEach piece: its area, and its own centroid from that origin.
Take the first momentsMultiply each area by its own centroid distance.
Divide by the total areaCentroid = ΣAx ÷ ΣA in x, and ΣAy ÷ ΣA in y.

The centroid is geometry only. It coincides with the centre of mass just when the density is uniform.
